Alternative-Fueled Vehicles The tableshows the numbers (in thousands) of alternative-fueled
vehicles Ain use in the United States from 1995 to 2011. (Source: U.S.Energy Information Administration)
Year | Number of vehicles,A |
1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 2011 | 246.9 265.0 280.2 295.0 322.3 394.7 425.5 471.1 534.0 565.5 592.1 634.6 695.8 775.7 826.3 938.6 1191.8 |
(a) Use a graphingutility to plot the data. Let t represent the year, witht = 5 corresponding to 1995. (b) A model for the datais
4615.36t − 8726.7
1 + 15.01t− 0.542t2, 5 ≤ t ≤ 21
where t = 5 corresponds to 1995. Use the model toestimate the numbers of alternative-fueled vehicles in 1996, 2006,and 2011. How do your answers compare to the original data?
(f ) Use the model topredict the numbers of alternative-fueled vehicles in 2016 and2017
